How the two plans work

SC-1 Rate I: Residential Service, New York City

  • In July the first 250 kWh a month cost 32.3¢ each; then 34.9¢ above 250 kWh a month.
  • An average New York home (784 kWh in July) goes past the first tier, so extra load such as an EV is priced higher.
  • Fixed charge: $23.91 a month.

SC-1 Rate III: Voluntary Time-of-Day, New York City

  • Mid-peak 8 am–2 pm, Peak 2 pm–6 pm, Mid-peak 6 pm–12 am on July weekdays; 4 of 24 hours carry the top price of 120.0¢.
  • The cheapest July weekday hour costs 12.5¢, so moving 1 kWh out of the top hours saves 107.5¢.
  • January weekdays range from 15.7¢ to 29.0¢.
  • Weekends follow a different schedule from weekdays.
  • Fixed charge: $23.91 a month.
